using DMSO and Ethanol at the same time

Anyone tried to use DMSO and Ethanol as solvents at the same culture media? in my case I have to use different supplements for media and one of them should be dissolved in ethanol, other ones - in dmso.

I'm not 100% sure but I think it will be safe - it would probably pay to run a test beforehand just using the solvents at the levels you would if you had added the drugs, to see if you can see any effect on your cells.
